MACHINE FOR THE MANUFACTURE OF CHOCO LATE CIGARETTES.

Application filed March 19, 1926, Serial No. 95,939, and in Germany July15, 1925.

This invention relates to machines for the manufacture of chocolatecigarettes coinprising a paper casing having a chocolate filling and hasfor its object to provide an improved machine of this character.According to the invention, rod-shaped pieces of chocolate filling aresupplied from a reservoir to recesses formed in the periphery of anintermittently rotated cylinder, each recess being adapted toaccommodate one piece of filling, and are then thrust by a rammer,adapted to move longitudinally. from the recesses into paper casingscarried by a ladle, the rod shaped fillings before entering the ladlebeing caused to traverse a cutting member adapted to remove anyirregularities from the rod-shaped fillings. It has been ascertained byexperience that rodshaped fillings, as supplied from the reservoir areirregular in form, being thicker in parts than in others andoccasionally of too great a diameter and even crooked, and it is toovercome this difficulty that the cutting member, through which thefillings are thrust, before arriving at the ladle, is provided. Thecutting member removes any irregularities and reduces the fillings tothe required diameter. The ladle itself is, according to the invention,composed of a number of thin tongues adapted to be pressed apart by therod-shaped filling. It is clearly desirable that the filling, shouldconform, as closely as possible, to the shape of the paper casing, andthat this filling should be prevented from sticking as it is liable to,for example, at comparatively high temperatures. Sticking of the fillingcould readily occur if a rigid ladle were utilized, but this isprevented by using the ladle constructed according to the invention.Furthermore, as a casing could not otherwise be made sufiicientlythin-walled for this purpose and provide a suitably firmseating of thefilling in the paper casing, the ladle is so guided as to enter thecasing, the rod shaped filling then being thrust into the casing.

In order that the nature of the invention may be more clearly understoodit will now be described with reference to the accompanying drawings, inwhich Figure 1 is a side elevational view in section on the line 1-1 ofFigure 2, of an embodiment of the invention, Figure 2 being a plan viewin partial section. Figures 3 to 5 are somewhat enlarged views ofportions of the mechanism illustrated in Figures 1 and 2. Figures 6 to 8are enlarged views of the filling ladle.

Referring now to the drawings itwill be seen that the machineconstructed in accordance with invention is used in conjunction wlth acasing drawing machine, constructed in a known manner, which supplies alength of easing 1. provided, if desired, with mouth-piece strips, apiece the length of a cigarette being cut off from the length of casingat intervals by shears 2. The empty casings are received by a cylinder 3which is provided at its periphery with a number of recesses 4, each ofthese recesses beingadapted to hold one casing (Figures 2 to 5), and thecylinder 3 is rotated intermittently so that the length of easing 1approaching the cylinder is always coaxial with one of the recesses 4.The casings accommodated in the recesses 4 are'now ready to receive arod-shaped chocolate filling. which is inserted therein at one end,while the casing in question is held fast by a finger 5 carried by alever 6, which is actuated by a cam disc 8, secured to a driving shaft10. through a crank lever 7. The filled chocolate cigarettes are carrieddownwards by the intermittently rotating cylinder, and prevented by aguard plate 11 in a known manner from falling. out of the recesses 4.finally fall on to an endless moving band 12, upon which they arecarried away.

The filling consists of pieces K (see especially Figures 1 and 5 to 8)of chocolate rod of circular cross-section which are located in areservoir 13, whence they pass out through a passage 14. A cylinder 15adapted to be rotated continuously by means of pulleys 16 and 17 fromthe driving shaft 10, is provided, in close proximity tothis passage,for effecting a continuous rotary motion of the rod shaped pieces K offilling so as to prevent the passage 14 from becoming blocked. From thepassage 14 the pieces K of filling pass on to a cylin-. der 18 or ratherinto recesses 19 provided at the periphery of this cylinder. Thecylinder 18 is rotated intermittently by means of a thrust rod 20carrying at one end a roller 21 which engages in the cam vgroove 22 of acam disc 23 secured to the shaft 10. The thrust rod 20 see Figures 1-and 2) is guided at one end by a member 24 and engages at its other endwith an arm 28 of a ratchet wheel and pawl 26 which while preventing anyunintentional reverse rotation of the cylinder 18 constitutes a devicewhereby rotary motion is transmitted to this cylinder.

The rod-shaped pieces K of chocolate filling disposed in the recesses 19of the cylinder 18 are each inserted by a rammer 27 located in a slider28 which is adapted to be moved longitudinally on a rod 29, intoitsappropriate paper casing. The longitudinal movement of the slider 28 iseffected by a thrust rod 30 which is actuated by a crank 31, secured toa crank shaft 32, the latter of which is driven through the pair oftoothed wheels 33 and 34 by the driving shaft 10.

A member 35 located between the cylinder 18 and the cylinder 3 anddisposed coaxially to the rammer 27 serves to guide the chocolatefilling, a cutting device 36' bein attached to the member 35. The rammer2% thrusts the pieces K of chocolate filling through the member 35 tothe cutting member 36, which removesany irregularities from the surfaceof these pieces and thus reduces them to the required diameter, thechocolate fillin onl entering the casing which may be orme of tissuepaper, after it has been thus prepared. During the filling process eachtissue paper casing is maintained in its appropriate recess 4 in thecylinder 3 by the finger 5.

Between the cylinder 3 and the cuttigng member 36 is a ladle 37, whichis illustrated on an enlarged scale in Figures 6 to.8, and which iscarried on an arm 38 of a sliding member 39, the latter of which isadapt-- ed to be moved horizontally on a guide member 40 on the frame ofthe machine, a lever 41, adapted-to be actuated by a cam disc 42,engaging with the member 39. The ladle 37 is therefore adapted to bemoved to and fro in a direction along the axis of the cylinder 3, thusprojecting into one of the recesses 4 on the periphery of this cylinderand bein withdrawn from this recess alternately. TVhen the ladleprojects into a recess 4 one end of the casing accommodated in thisrecess is caused to run up on the ladle 37, the other end being pressedagainst a plane surface 43 which prevents longitudinal movement of thecasing.

The ladle itself comprises a base plate having a plate 44 securedthereto, spring tongues 45, of which in the example illustrated thereare four, extending through a central aperture in the base plate 37, andbeing secured to the late 44. The ladle 37 approaches the cylin er 3 andthe rammer 27 then thrusts a piece K of chocolate filling through thecentral aperture in .the base plate ofthe ladle 37. The piece K offilling presses the spring tongues 45 apart (see especially Figures 8-and 7) and enters the tissue pa er casing, the insertion of the piecesof lling into the casing 2 being facilitated by the tongues 45 which arearranged to be sufficiently thin and weak. (dare should be taken thatthe tongues 45 do not constitute an appreciable obstacle to the motionof the pieces of filling which, consisting as it does of chocolate, hasa tendency to stick when thrust through an aperture.

After each casing is filled, the finger 5 is raised and the cylinder 3continues to rotate intermittently, the filled casings being deliveredon to the endless band 12.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat Iclaim is:
